This reminds me of my late friend and I reading saucy postcards outside a shop in Great Yarmouth years ago. We were hysterical as we read each one, really loud laughter, so much so that the assistant came outside and we thought we were going to get chased. But no, she said she hadn't heard laughter like it in years and was a tonic to her----and good for business as it drew quite a few people.
Needless to say, I went inside and bought a number of the postcards to keep and now and again I look through them and smile, thinking of that day. How anyone would not find them funny would be beyond me.
Thank God for my sense of humour ! Though a lot has gone since my friend died.
